Everytime I play Crysis or GTA 4 my Computers shuts off after 10-15 min of game play. I have been checking my temps while I am playing the games and my CPU sits @ 50-52 c and my GPU max 80 c. When I play FC2 I have no issues?? Whats up ? is it my Power Supply. See my rig in the sig!

That would be my first guess. Only because the same thing happened to me in the past. I thought for sure it was temps, but none of them were very high. When I put in a new PSU the problem stopped. Although I did start getting power warnings. (you may want to monitor voltage if your MB lets you).
I don't think I can with this old MB. Everything else runs fine. The PS is only 3 months old? It just started 1 month ago.
Head over to your local electronics store and pop in a new PSU. If it's not the problem, just return it. Easy diagnostics!
I got a good feeling it is the motherboard. I am having the same Mobo but with Rev 1.0, and have been having sudden shutdowns about a month ago. I got a buddy who had the same board and hardware as we purchased at the same time, well, his mobo died 6 months earlier. It had sudden reboots happening until one day, it's dead. He did changed his PS about a year back as the first PS died.
My other friend told me that his friend had the same mobo but not sure of the Rev and it also have sudden shutdowns.
My sudden shutdowns occurs quite consistently about 5 to 15 minutes upon boot up. If it shuts down, occasionally it will self reboot. If not, I hv to manually turn off the mains power for about 15 secs before I can re-start the PC. Normally, after the sudden shut down or re-boots, it will be stable. My mobo is 3 years old in Oct 2009.

I think I am going try a new mobo--Might just go pick up a Cheap Gigabyte P43-- I don't want to over do it. I wanted to upgrade to the i5/i7 in about 6 months. If that doesn't work then I will get another powersupply. I bought the P965 Mb used for $35.00 and it has treated me well since then. Unless any others on here feel like I am wasting my time and I should get a new PS?

If your entire computer is shutting down, and it is a symptom that you can repeat, then it is most likely your PSU overheating.
Once you start gaming and the amps start getting pushed thru the PSU your PSU starts heating up...as it heats up its efficiency starts going downhill, which means it has to push even more amps which then causes it to heat up even faster.
There will be an overcurrent protector inside the PSU, and no doubt it is tripping which then shuts down power to everything connected to it.
If it was your GPU then I'd expect the symptoms to involve graphic artifacts before getting to the point of shutting down the computer itself.
Also if it was your mobo then I would not expect it to be a repeatable deal. It would fail more randomly and not necessarily with GPU intensive stuff.
Just my $0.02.
I have a CM 690 case. The PS is at the bottom of the case and the fan draws air from the bottom. I wonder if it is overheating? I can try to flip it up the other way so it is able to draw more air. And when the PC shuts down, I can turn it right back on there is no waiting period.
Also the GPU and CPU is not overheating, but I will dial everything down to stock levels and see how it does. the CPU voltage is at 1.36 not that high.

Is the case sitting on carpet or some hard-surface? In other words how much clearance does the intake grill on the PSU actually have to the floor?
I just got an ABS black pearl, similar config. I initially had it sitting on a short-hair carpet, not thinking about the clearance. Then I noticed my hdd temps were 41C, seemed hot to me.
So I put a wood board underneath the case, running the whole length so now at least the underside gets the engineered/designed clearance. Changed nothing else, my HDD temps are now 38C, a full 3C cooler just because of the under-case clearance difference (at most was 0.25in difference).

Well I brought everything down to stock levels (2.4 Ghz) on the CPU overclock and it runs fine. I played Crysis for 30 min with no problem. I had my Q6600 @ 3.2 Ghz @ 1.36 Volts 356 X 9. The temps never reached above 60 c with Prime running. I left the NB (MCH) voltage alone and my memory from 800 to 890 MHz @ 1.9 Volts. Any ideas?
I used to to have the DS3 myself, the north bridge gets very very hot as I remember but your cm 690 case has good vent. btw, i don't think it's your PSU, that 750W can handle the load. is your 280 OC experiencing temperature problems? check that first, run furmark and check temperature on that thing. just to be sure it is not the gcard that's crapping out.
Well first if I were you,I would test it some more at default settings.This kind of errors are random-sometimes if might shutdown after 15 minutes,sometimes after 2 hours
Make sure you test atleast for 2 hours before deciding what to do next
My bet is it's psu-in 90% of the cases when pc just shut down suddenly its psu related.
Because unstability of any other component should cause a freeze,a blue screen or a restart- not a shut down
Is it posible that your psu is broken-because 750w is more then enough for your system.If it's broken maybe overclocking and pushing more voltage pushed it over the age ?
I would test the system at default for 2-3 hours,gaming,and then if it doesn't shut down,slowly up the overclock by small amount and see what happens.See what exactly is causing the unstability.It may be the memory,how many slots are taken ? It it's all 4,even that slight 90 mhz might cause the problems.
Memory should be at 2.1 atleast when overclocking not 1.9....

Hm I just saw you have 6gb...that's very strange combination for c2q system..you should have either 4 or 8 gb...this means you cant use dual channel afaik...
Is it 3x2gb ? You are probably better off just using 2x2gb and selling one 2 gb stick as your pc will work faster that way

Well, since your previous overclock wasn't working, I'd start at square one with this thread. That should allow you to figure out what you overclock limiter is (FSB, memory, CPU, etc.).
I will game for an hour or so at stock speeds to see what happens. My Ram combo is 2x2gb and 2x1gb sticks all four slots are filled. The stock recommend volts for that ram is 1.8 v @ (800 mhz and 5-5-5-18) -- Would I really need to bring it too 2.1 v for + 90 mhz and 5-5-5-15) I also have installed an Vantec NB HSF on the NB to keep it cool, I noticed it was running rather hot before I installed it. I will use the Noob OC guide to see what I did wrong-- I have OC many CPu's beofre w/ no probs. I also have 6 Case fans installed and tied to a zalman fan controller so airflow in the case is exceptional.
I really think it's your ram.
You cant overclock the system with configuration like that.It's not overclock friendly at all.
First,it's best to use only 2 sticks when overclocking not 4 as it makes the memory more stable.And you even use different memory modules....
You will need atleast +0.3 or +0.4 volts to the memory to make this stable
This means 2,1 or 2,2 volts
You dont have to worry about damaging memory they can handle up to 2.2
You can test if its memory by taking out those 2x1 gb modules and only leave 2 modules ( 4gb )
I am sure your computer will not shut down then

There's nothing wrong with running 6gb or 4 sticks of ram...
If it's not temps I'd say motherboard or PSU like the others. But keep it at stock and see if it checks out.

I had a similar problem. I would get half way through a movie when blam, the comp would just shut down without warning. After much grief and waste, turned out to be the MB. It was a Gigabyte and I haven't bought one since.
